/dev/sdb: No such file or directory (but /dev/sdb1 etc. exist)

http://unix.stackexchange.com – I'm not sure what is wrong here but when running fdisk -l I don't get an output, and when running fdisk /dev/sdb # I get this fdisk: unable to open /dev/sdb: No such file or directory I'm running Ubuntu 12.10 Server Can someone please tell me what I'm doing wrong? I want to delete /dev/sdb2-3 and just have one partition for sdb The only thing I've done differently with the setup of this server is use ext4 instead of ext3, I figured the extra speed of ext4 would help since I am using SSDs now root@sb8:~# ll /dev/sd* brw-rw---- 1 root disk 8, 1 Nov 23 14:58 /dev/sda1 brw-rw---- 1 root (HowTos)
